The hopper I0 is adapted to maintain a sup ply: of fluent material widely'used in repairing or originally installing asphalt, roofing. The material employed is fluent whenmaintained above; a temperature higherthan normally found.

asclimatic.

The hopper-1 has apairof-sideswithpivot pins 22 and i4 secured thereto. The hopper has an inlet land a, discharge opening or outlet l8.

A heater consisting of heating elements disposed in cases 20 and 22', is secured to the hopper Hi adjacent the outlet l8. Accordingly, while theheater is operative, the-heat is applied to the hopper at the most essential place, namely the discharge opening region. Conventional circuitbreaker type'contr'ol is employed for operation of theheater.

The hopper is passed throughan openingin a base generally indicated at 24. This base consists ofstructural members of known description. A pair of wheels -26.an'd 28 are disposed on an A support is formed in two parts and secured to the base. Each part consists of structural members connected together by means of bolts, welding, riveting or the like. The almost vertical structural member 29 has its lower end secured to the base and its upper end secured to a substantially horizontal structural member 3|]. The structural member- 30 is secured at its, other end to, the axle 32. The connecting cross member is secured to the base (see Figure 6) and also .to the substantially horizontal structural members 30. Upstanding portions -36.and 38 of the cross member also form a part of the support.- The upper, ends of the upstanding. portions are secured tothe structural framing members land 4! whichflare legsof the U-shaped member 42. This U-shaped memberhas bearings 44 and .46 secured toits. web accommodating the shaft 48.

The shaft 48 has a knob 50 at one end thereof and a drum 52 secured adjacent the knob. The drum has a flexible member, suchas a cable 54, secured :at one end thereto and at the other end to the upturned end of abar 56. The downturned opposite. end of the bar has aspring 58 secured. theretowhich is also secured to a part of said suDl Ort.

' A valve 60 consisting of aplate having angu larly connected sections is secured to thehopper by means of a hinge .62. Thevalve is disposed (Figures 5 and 7) 64 has its lower transverse end secured in bearings 66 and 68 which are secured to the valve 60. The substantially straight portion 64 has its upper end adjustably secured to the bar or rod 56 intermediate the curved ends thereof. A pair of nuts are employed to adjustably connect the link 64 to the member 56, one nut being disposed on opposite surfaces of the member 56 so that they are employed to lock the link in place.

From the foregoing, operation of the valve is summarized as follows: rotation of the shaft 48 by the knob 50 causes the cable 54 to be wound on the drum 52. pulling it against the opposing force of the spring 58 which is employed normally to maintain the link 64 in one position, that is, the valve closing position. There is suflicient friction in the bearings to hold the valve GI] in the selected adjusted position.

A motor I is disposed on the base and base; shaft projecting therethrough. This shaft has a double sheave, consisting of pulleys I4 and 16 fixed thereto, below the undersurface of the base 24. 'A counter shaft I8 is mounted in a suitable bearing and carried by the base. This counter shaft is rotated by the motor I0 through a transmission consisting of the pulley l and a pulley 80, with a belt 82 entrained around both of these pulleys. The bearing in which the shaft 18 rotates'is on a swinging arm 84 which is pivoted to the base 24. Upon operation of the swinging arm 84, the belt 82 is selectively tightened and allowed to slip, whereby the control of the tran mission operativeness is attained. The swinging arm 84 is passed through an opening 86 (Figure 5) formed in the base 24 having a number of teeth 88 extending therein Theseteeth are engaged by the dog 90 which is fixed to the swinging arm 84 so that selected pivoted positions of the arm 84 may be attained and kept An eccentric 92 (Figure 3) is secured to the pulley 80 and a pitman 94 i secured to the eccentric. The pitman is also secured to a hanger 96 which is carried by the hopper whereby upon operation of the motor, the transmission transfers the torque of saidmotor to oscillatory movemerit of the hopper about the pivot pin I2 and I4 as an axis.

A'handle 98 is secured to the base appropriatelyto manually operate the device.

A brush assembly is disposed at the end of the base opposite from the wheel 26 and 28. This brush assembly consists of a spreader brush Hill which is fixed stationary on a mounted assembly I02. This assembly includes a plate which is bolted to the base and suflicient cross members to actually support th'e brushes. The spreader brush IE0 is stationary and includes a center section together with angularly disposed 'end pieces or brushes, I04 and I06. Another stationarybrush I98 is secured to the mounting assembly I92 but spaced from the brush I00. The brush IE8 is used as a follower brush and is substantially parallel to the brush I00.

Anumber of brushes H0, H2, H4, H6, H8 and I2!) are rotatably mounted on' suitable small shafts on the mounting assembly. Each of-the rotary brushes has a gear secured thereto and the gears are enmeshed. Accordingly, rotation of one brush causes rotation of all of the others of the rotary brush group. y

"Thi rotation is imparted by means of the motor 10. The belt I22 is entrained around the pulley I4 and also around the pulley I24. The

This displaces the member 56,

4 pulley I24 is rotatably mounted on the shaft I26 which is suspended from the bracket I28. This bracket is carried by the base 24.

A pulley I30 is also secured to the shaft I26 and has the belt I32 entrained therearound. This belt is drivingly connected with the pulley I34 which is disposed on the shaft I36. The shaft I36 supports the brush III] of the rotary group, whereby, upon operation of the motor I0, rotation of all the brushes of the rotary group is obtained.
